problem of make_priors_envirotlas.py

Hello, your article is very helpful. I have some problems in the reproduction process, I hope you could help me. I want to get the prior of the EnviroAtlas dataset, through make_priors_envirotlas.py. But I don't know how to get the csv file in ea_data_splits_dir = '/home/esther/qr_for_landcover/enviroatlas_data_splits'. Looking forward to your reply, thank you!
